2 Claims. (Cl. 533) This invention relates to means and mechanism of the shaft l2 and container. In practice the for producing an infusion or decoction especially period of such rotation may be, say for three of coifee and has for its main object to provide a minutes, more or less, according to the desired simple and economical construction for use in the strength of the decoction and the degree of grind 5 home. A further object is to provide means in of the icofieewhen the container and its contents 5 the coffee pot cooperating with the operation of are rotated in the hot water. the ground cofiee container whereby a swirling The character I"! designates a lever having and other motions of the hot water are set up and thereon a stop pin Il said lever pivoted to the the infusion or decoction more rapidly and satisgea t a ea f0 arresting y the Contact 0f factorily accomplished than heretofore.

I find that In the instance shown the motor includes a gear the best infusion is obtained by making it in hot train [4 and a volute spring l5, the latter adapted water but not boiling because in this way importo be wound up to the extent desired by a finger tant volatile elements of the coffee are not driven piece It and released at will to cause the rotation off. Hence, with my construction the hot water 55 tends topenetrate the perforations of the container and the grounds therein from all directions. It may be further noted I have found that where the volatile elements and aroma of the coffee are not driven off as by boiling the water the infusion is better preserved, and it is well known that an ordinary left over boiled water infusion of coffee is practically unpalatable as compared with an infusion immediately made and used. However if the user prefers to use heat to boil the water while rotating in the container that will be practicable.

It is obvious that instead of a spring actuated motor an electrically operated motor can be employed where the required electric current is available.

The forms and sizes of the parts can be changed without departing from the gist of the invention as claimed.

What I claim is:

1. In an infusion making means such as described, including a container for water and a removable cover therefor, a perforated receptacle for the material from which the infusion is to be made, said perforated receptacle being a tubular portion closed with substantially flat ends extending in vertical planes, and a vertical rotatable shaft connected with said receptacle between said vertical ends, said water container having fixed therein to the wall thereof a substantially vertical breaker rib, whereby when said receptacle is rotated water in said container has imparted to it by said ends and breaker a swirling and rising and falling movement.

2. In an infusion making means such as described, including a container for'water and a removable cover therefor, a perforated receptacle for the material from which the infusion is to be made, said perforated receptacle being a tubular portion closed with substantially flat ends extending in vertical planes, one of said ends constituting a removable cover, and a vertical rotatable shaft connected withsaid receptacle between said vertical ends, said water container having fixed therein to the wall thereof a substantially vertical breaker rib, whereby when said receptacle is rotated water in said container has imparted to it by said ends and breaker a swirling and rising and falling movement. 7
